To @ZZ whom t may concer/n:

Be it known that CHARLES E. MCC/LAL a citizen of the United States, residing at the city of Los Angeles, county ot' Los Angoles, tate 0f California, have invented new and useful Improvements in Demountable Rini-Securing Devices, of which the following is a speciiication.

My invention relates to means for securing a demountable rim upon a vehicle Wheei and the object thereof is to provide a device for that purpose Whose parts are all connected and by the use of which a rim may be quickly attached upon or detached from the feliy.

lin the drawings forming a part of this applieation:

Figure is a side View of my device in its inoperative position and detached from the `Wheel. i

Fig. 2. 'is a section of a portion of a 4Wheei showing my device in its inoperative position, one side of the casing being removed for ciearness of illustration.

Fig. 3. is an end View of the device in its operative position detached from the wheei.

Figs. t and 5 are views of detached parts.

Fig. 6 is a section of a portion of a Wheel and the casing showing a slight modiication ora my device.

Referring to the drawings: 10 is the spoke, 11 the teily and 12 the :telly rim, all of any approved construction. 13 is the outer casing, la the inner tube and l5 the metal tire rim.

My rim securing device consists ci? the tollowing parts; to Wit, a U-shaped metal casing 16 in the inner end of which is pivotally ionnted a short link 17. A longer link 18 is pivotally connected at its inner end to iink i7. The outer end of link i8 is pivotaily connected to the rear end of head i9 by pivot pin 20 which projects on each side of the link a distance equal to the thickness ot the metal comprising the casing. Head 19 is also pivotally connected to the casing by pivot pin 21 which projects through slots 22 in the casingv so that the outer ends of the pin are flush with the outer faces of the casing. Slots 22 could be straight as shown by slot 2? in Fig. 6. Pin 20 passes through hole 23 and pin 21 passes through hole 24- in head l i9. These holes are shown in Fig. 5. The outer end ci link 17 is preferably rectanguhead is then positioned by forcing its nose between the ieliy rim and the demountable rim. There are as many of these devices as may be required. When the head is positioned the center of the pivot betweenL the links passes a little nearer to the folly than the center of the pivot which connects the shorter link to the casing thereby locking the head properly positioned. The rectangnlar shape of' the outer end of the shorter link enables the operator to place a Wrench thereon to position the head, and also to release it when desired, thereby making the action ot putting on or taking ofi' the demountable rim Very easy of accomplishment with the minimum consumption of time. As all the parts are connected and securely held on the felly 'there is no danger of losingl any ot the parts of my securing device, and they are ready and in place for use when Wanted.

ln some wheels there is a Wedge ring which enters between the demountable rim and ielly rim. When such rings are used the nose would be cut od on the plane of the outer face ot the Wedge ring when positioned for use as shown in Fig. 6.

Having described my invention l claim:

l. d demountable rim Securing device comprising, a tti-shaped metal casing having slots in its sides near the outer end thereof; means to secure said casing to a folly; a shorter link pivotally mounted in the inner end of said casing; a longer link pivotally secured to the outer cnd of the shorter link; and a head pivotally secured to said longer link and to the outer end of the casing, thc pivot connecting said head and casing Working in the slot in the casing, and the pivot connecting the head and casing passing to the outer face of `the casing and being adaptgle mounted in said easing,'a head pivotay ed to slide on the edges of the easing when connected to said toggle, and a pin in said the head is moved. head projeetin' into the slots in the casing. 10 2. A demountable rim securing device In Witness tlavt claim the foregoing I 5 comprising a casing adapted t0 be secured have heeunto subscribed my name this 9th upon the fely of a vehicle Wheel, seid casday of Agugust, 1917. ing having slots in the sides theleo; a. tog- CHARLES E. MCCLAY.
